91794255 divided by 688 
We want to figure out the number of times 91794255 can be divided by 688.

On to step 1:
If we divide 9 by 688, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 688

Moving on to step 2:
688 goes into 91 0 times with a remainder of 91.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 91 to get 91.
Fetch the next digit (7) from the dividend, attach it to 91 and continue: 917 / 688

Let's proceed to step 3:
688 goes into 917 1 times with a remainder of 229.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 688 away from 917, we end up with 229.
Grab the next digit (9) from the dividend, add it to 229, then carry on: 2299 / 688

On to step 4:
The number 688 fits into 2299 3 times, leaving a remainder of 235.
Use 3 as the next digit of our solution. 
Result so far: 13.0
The remainder is 235 after subtracting 2064 from 2299.
Grab the next digit (4) from the dividend, add it to 235, then carry on: 2354 / 688

Step 5:
When dividing 2354 by 688, we get 3 with a remainder of 290.
Put 3 as the next digit of the answer. 
Result so far: 133.0
If we take 2064 away from 2354, we end up with 290.
Grab the next digit (2) from the dividend, add it to 290, then carry on: 2902 / 688

On to step 6:
If we divide 2902 by 688, we get 4 and a remainder of 150.
The number 4 becomes the next digit in our result. 
Result so far: 1334.0
If we take 2752 away from 2902, we end up with 150.
Fetch the next digit (5) from the dividend, attach it to 150 and continue: 1505 / 688

Step 7:
688 can be fit into 1505 2 times, resulting in a remainder of 129.
Use 2 as the next digit of our solution. 
Result so far: 13342.0
Subtracting 1376 from 1505 leaves us with 129.
Grab the next digit (5) from the dividend, add it to 129, then carry on: 1295 / 688

Step 8:
1295 divided by 688 is 1 with a remainder of 607.
Record the quotient 1 as the next digit in the result. 
Result so far: 133421.0
Subtracting 688 from 1295 leaves us with 607.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6070, and continue the process.

Let's proceed to step 9:
688 goes into 6070 8 times with a remainder of 566.
Put 8 as the next digit of the answer. 
Result so far: 133421.8
Subtracting 5504 from 6070 leaves us with 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

On to step 10:
If we divide 5660 by 688, we get 8 and a remainder of 156.
The number 8 becomes the next digit in our result. 
Result so far: 133421.88
Subtract 5504 from 5660 to get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Our division results in 133421.88 with a remaining 0.156.
